The comparable other would be linking, not compiling.

We will find ourselves in a case where the compression has used a 
version of a Javascript file with a bug in it, the bug has been fixed in 
the RPM, but Horizon will still need to live with it.  The right thing 
to do is make it possible to recompress on the remote machine.

We can certainly do this at RPM install time, and make it a manual 
process to recompress.  That will lead to support requests, but at least 
it is solvable.

So, I think the realistic approach is to compress when we install the 
RPM, provide docs for how to manually recompress, and work towards 
making this sane in to do in systemd.  The first two are packaging tasks 
and should be straight forward.  The third we should work on for the 
Liberty release.
